We show information related to new account locking, but be prepared
for an even richer account details view here, i.e. including information
regarding password reset and account/email verification status.

Number of previously logged failed login attempts as well as lock condition
and lock behaviour are evaluated and displayed to the user.
Optional exponential lock time prolongation can be used to further reduce
effectivity of attempted brute-force attacks on user passwords.

These will get used later i.e. by admin operations in account locking code,
where we can't easily derive this account information from req object,
as that has been only available per user within authenticated sessions.
